Rhino into GSA using geometry gym

Hi, I am new to geometry gym, I have to analyse this building in GSA, which I created the form using Rhino thought I could export it using grasshopper. But since I drew the shape not using grasshopper, I’m not sure how to export it using Geometry Gym… do I have to create the form again using grasshopper?

Thank you!

Sorry, for some reason I didn’t get notification of the post.

Can you please either attach or email a representative sample of your model?

It’s possible to collect rhino inputs into Grasshopper, but it will be much easier if you have centerlines rather than solid objects.
